As the plane heads toward Halifax, the wind speed supports the flight path
resulting in an overall improved speed
Conversely, during the return trip, the wind will resist the plane's motion, decreasing the net speed
The total journey lasts 13 hours
of which 2 hours was dedicated to the mathematics discussion
Consequently, the total flight time is 13 - 2 = 11 hours
Now we apply the formula to calculate the time for traveling to Halifax

Time needed to return

Let’s look at the total time


Here d = 3000 miles



By solving the derived quadratic equation

the plane's speed calculates to 550 mph
This involves circuit analysis through simplification of the resistors and capacitors. We need to determine the time constant for each circuit in figures A, B, C, D, and E. This leads to ranking the duration the bulbs remain lit from longest to shortest based on each circuit's time constant. The ranking for the time constants is C > A = E > B > D. Capacitance plays a pivotal role in electrostatics, and devices called capacitors are vital components in electronic circuits. When more charge is applied to a conductor, the voltage escalates proportionately. The capacitance of a conductor is quantified as C = q/v. Adding resistors in series raises resistance while parallel configurations reduce it, conversely increasing capacitance in parallel and diminishing it in series. Thus, circuits with greater time constants take longer to discharge.
Answer
Given:
Wavelength = λ = 18.7 cm
= 0.187 m
Amplitude, A = 2.34 cm
Velocity, v = 0.38 m/s
A) Calculate the angular frequency.
Angular frequency,
ω = 2π f
ω = 2π x 2.03
ω = 12.75 rad/s
B) Calculate the wave number:
C)
Since the wave is traveling in the -x direction, the sign is positive between x and t
y (x, t) = A sin(k x - ω t)
y (x, t) = 2.34 sin(33.59 x - 12.75 t)
